Sounds like the best thing to do and I think I,ll do the same, I pick up my ps4 next fri (UK) and was seriously considering purchasing this but from what I have read and heard I'm not gonna even look at it. Killzone and assassins creed for me.

No. The primary ps4 it's activated to, it stays on that one. On that note, game sharing is no more as well. My clan mate and I have game shared for 5 years now, he upgraded his ghosts from ps3-4. I already had gotten ghosts from him on ps3, he upgraded so I downloaded it on my ps4 also. Didn't work, could only be played if I was on his account. Pretty bumming

Id say any cod game since cod4. Or possibly all of them. But don't get me wrong, bf4 is complete junk at the moment. But when it does work on ps4 for the few moments, you can tell it will be incredible when they patch things up.
